Go tell your brotherhood this first slip of mine,

All to-day's tale, how you detected Sludge,

Behaved unpleasantly, till he was fain confess,

And so has come to grief! You 'll find, I think,

Why Sludge still snaps his fingers in your face.

There now, you 've told them! What 's their prompt reply?

"Sir, did that youth confess he had cheated me,

I 'd disbelieve him. He may cheat at times;

That 's in the 'medium'-nature, thus they 're made,

Vain and vindictive, cowards, prone to scratch.
